METHOD FOR EFFICIENT SOUND FIELD CONTROL OF A COMPACT LOUDSPEAKER ARRAY |
摘要 |
A method for optimizing the design and sound field control of a compact loud-speaker array, which includes a plurality of loudspeakers located on a closed loudspeaker surface and the control of the emitted sound field by the loudspeakers within a limited reproduction subspace, having the steps of capturing the sound field using a plurality of microphones and adjusting filter coefficients that modify the alimentation signals of the loudspeakers to minimize the difference between reproduced signals captured by the microphones and target signals describing a target sound field. A conical reproduction surface encloses a reproduction subspace is defined such that the apex of the conical reproduction surface is within the closed loudspeaker surface. Loud-speakers are positioned on a limited loudspeaker surface and the closed loudspeaker surface. The microphones are located on a limited microphone surface defined by the intersection of the inner volume of the conical reproduction subspace and the closed microphone surface. |
